The phylogeny of termites (Dictyoptera : Isoptera) based on mitochondrial and nuclear markers : implications for the evolution of the worker and pseu…
2008
A phylogenetic hypothesis of termite relationships was inferred from DNA sequence data. Seven gene fragments (12S rDNA, 16S rDNA, 18S rDNA, 28S rDNA, cytochrome oxidase I, cytochrome oxidase II and cytochrome b) were sequenced for 40 termite exemplars, representing all termite families and 14 outgroups. Termites were found to be monophyletic with Mastotermes darwiniensis (Mastotermitidae) as sister group to the remainder of the termites. In this remainder, the family Kalotermitidae was sister group to other families. The families Kalotermitidae, Hodotermitidae and Termitidae were retrieved as monophyletic whereas the Termopsidae and Rhinotermitidae appeared paraphyletic. All of these result…
The fine structural organization of sternal glands of pseudergates and workers in termites (Isoptera): a comparative survey
2008
1873-5495 (Electronic) Comparative Study Journal Article; Thirty-nine species belonging to different families of termites are studied to give a comprehensive view of the evolution of the sternal glands. Several modifications occurring at cuticular and cytological levels are described in neuter castes. The outer epicuticle is always pierced by epicuticular pores. In advanced termites the epicuticular filaments greatly increase in number and length creating a thick layer. The pore canals gradually enlarge while the cuticle changes into a lattice structure lining an extracellular space in which the secretion is stored. Two classes of cells are present in basal termites (Mastotermitidae, Hodote…
The Intestinal Yeasts
2005
Yeast isolates were obtained from the hindgut of the lower termites Mastotermis darwiniensis (Mastotermitidae), Zootermopsis angusticollis, Zootermopsis nevadensis (Hodotermitidae), Neotermes jouteli (Kalotermitidae), Reticulitermes santonensis, Heterotermes indicola (Rhinotermitidae) and the roach Cryptocercus punctulatus (Prillinger et al. 1996). The monosaccharide composition of the cell wall, the ubiquinone system, partial sequencing of 18S ribosomal DNA and the ultrastructure of septal pores indicate that most yeast species belonged to the Endomycetales. They were assigned to the genera Candida, Debaryomyces, Pichia and Sporothrix. Other species showed affinities to the Basidiomycetes …
